Specification of Letters Patent.

Patented May 1, 1906.

Application filed May 17, 1904. Serial No. 208,344

' To all whom it may concern:

Be it known that l, LEON P. LOWE, a citizen of the United States, residing at San Franciscofin the county of San Francisco and State of California, have invented certain new and useful Improvements in Apparatus for Separating Residues from Liquids, of which the following is a specification.

My invention relates to an improved apparatus for separating carbonaceous and hydrocarbonaceous residues from lic uids containing the same, such liquids resulting from the washing of commercial gas in its inanu facture.

My invention therefore resides in the novel construction, combination, and arrangement of parts for the above ends hereinafter fully specilied, and particularly pointed out in the claims.

[n the accompanying drawings, Figure l is' a longitudinal section of the apparatus. l 1g.

2 is a plan view of the same. Fig. 3 is an enlarged transverse section of the same.

Referring to the drawings, 1 represents a tank into which the liquid containing the residues is conducted by a flume 2. In the bottom of said tank, at the end next said lhune are arranged a series of graduated partitions 3, increasing in height according to their distances from the iluine. These partitions successively arrest the solid particles suspended in the liquid and cause them either to sink to the bottom or to rise to the top of the liquid, according to their speci'lic gravity. The lighter residues rising to the top pass between transversc beams l, extending between the sides of the tank, and are by them arrested, the liquid llowing on through the tank underneath the residues. In like manner at the end of the tank farthest from the ilumc is a second series of depend ing vertical 'iartitions 5, increasing in depth according to their distances from the lluine, and the residues which have escaped the aforesaid partition and beams are arrested by these partitions 5 and for the most part rise to the top ofthe Water.

6 represents scrapersattached 'to endless chains 7, running around wheels 8 on shafts 10, one of said shafts being driven by a pulley 11 from-any suitable source of power. These scrapers scrape oil the tops of the residues and push them over the side of the tank, depositing them upon a pile at said side, said pile being shown at 12 in Fig. 3. Thus at all times the accumulations of these residues at the top of the liquid are removed from the top as fast as they accumulate underneath the masses of residues. The liquid. thus separated from the residues flows through screens 13, by which it is filtered, and linally passes out by a channel l 4.

I claim-- 1. In an apparatus of the character described, the combination of a tank, an inlet 'and an outlet for the liquid containii'ig the residues, a series ,of vertical partitions increasing in depthaccording to their distances from the inlet, and a scra 'icr scraping the residues from the surface of the liquid, substantially as described.

'2. In an apparatus of the character described, the combination of a tank, an inlet and an outlet for the liquid containing the residues, a series of upwarilly-exlending partitions increasing in height according io their distances from the outlet, :1 second series of downwarilly-extcnding partitions increasing in depth according to their distances there from, and scrapers moving li'ansversetv or parallel with the pz'u'tilions, for scraping the residues from the surface of the. liquid. substantially as described.

In witness whereof I have hereunto set my hand in the presence of two subscribing witnesses.
